I have a 24 channel audio output device (a MOTU 24IO,) and I'd like
to assign one AudioQueue per output channel, so I can play different

Thanks to Bill, I can now play audio on the first channel of my MOTU
by changing the CurrentDevice property of the AudioQueue.
My three questions are:
1. How do I select a particular channel for this multi-channel
AudioDevice?
We don't really have a way to do this at the moment with audio queue
2. How do I continuously loop a given audio file on a particular
channel.
just loop the buffers you provide (when you get to the end, the next
buffer you enqueue is read from the beginning again)
3. Architecturally, would the most efficient approach be to create
separate thread for each channel and then have each thread create
its own AudioQueue?
Thanks,
Bob
